When we are automating and maintaining tests we need good feedback on test runs. Playwright gives quick and useful feedback in its Trace Viewer which provides feedback on the run of tests. Trace Viewer’s feedback is one reason I like automating tests with Playwright. Through Trace Viewer you can: If a Playwright test fails, Trace …

Sometimes you need to assert that Playwright tests are not running too fast!
Tests that are automated in Playwright run fast, which is great. However, sometimes they run so fast that assertions need to be used to stop the test being flaky. Playwright uses Auto-waiting to help it run tests fast. Auto-waiting means that Playwright performs several checks before making an action, for example, it checks that an …

Writing test automation standards is a journey, not a destination
I have started to automate tests in Playwright with TypeScript. I am now writing standards for the tests. I view writing the standards as a journey because I am adding to the standards as I learn more. I have started to create these standards because: I have found lots of useful advice in testing and …

Why I don’t record automated tests
Recently it was pointed out to me that Playwright has a test generator and that I could use it to record tests. Many automated testing tools include a tool or extension that can be used to record tests. I don’t find them useful. My experience of using tools to record tests is that they record …
Automated tests do not have to be flaky.
When I create or maintain an automated test I use a “learning loop” so that I learn from the test results. This enables me to create stable test packs that return accurate results. I automate tests with Playwright using TypeScript and with the low code tool Ghost Inspector. The “learning loop” is the same for …
Make test automation easier with better feedback for parameters with TypeScript
We can make it easier to automate tests by giving feedback if incorrect values are passed as parameters. Developers can get feedback when they try to pass an invalid parameter if I use union types when using TypeScript. I have been using TypeScript to automate tests with Playwright. We often pass strings to functions as …

Improve test coverage by parameterising tests with Playwright and other tools
Automated tests can be run multiple times with different values by parameterising tests. Parameterising your tests can improve test coverage because a value in the test can be parameterised which means that the test can iterate through a number of values. This enables one automated test to cover a number of test cases. You could, …

First impressions of test automation with Playwright
I have recently automated some tests using Playwright. It is a free-to-use Node.js library created by Microsoft that is designed to be used to automate end-to-end testing. Playwright supports chromium, WebKit and Firefox, and, by default, all tests are run on all three browsers. Tests can be run in headless mode. It supports, Java, .Net, …
